It's a hard one, since I like SUP surfing and also racing and downwind. So maybe it's time for 2 boards quiver, thread?

My one board SUP Surf quiver is the Infinity B-Line 7'11 x 27'' (85 liters). It's my day to day board and I use in all conditions: big waves, small waves, mushy waves, glassy waves, etc. It's such a perfect board!
My one board race quiver is the SIC RS 14'0 x 24.5''. Since it's very stable for its width and a true all-water board I used it this year in every conditions: flatwater, surfing, beach race and downwind. I'm going 23'' next year but I will also add a Bayonet 17'1 for downwinds. So If I had to settle for only race board only it would be the 24.5
